Boston University Rocket Propulsion Group recently test fired their Iron Lotus rocket engine. Developing ~2500lbf (11.1kN) of thrust, the engine was tested for 1 and 3sec burn times.
As the name implies, the engine is a steel heat sink engine, not intended for long duration firing and primarily used for ignition testing, before the (flight) regen Lotus Dev 2 engine is tested.

The engine has increased in thrust from 1,500lbf to 2,500lbf which has enabled the use of a single chamber assembly instead of the dual clustered setup originally designed. The team has also turned to Triton Space Technologies for their main valves, which will be pyro actuated poppet valves. (Triton make a range of valves and products so is worth a look for your next rocket project)

Lotus Dev 2 features 233s Isp and 2,500 lbf thrust at sea-level. A single Lotus engine will replace the dual LD1 cluster on Starscraper pic.twitter.com/D23HGWFM6r
